IMPRovEMENT IN FouNTAlN-NozzLEs.

Specification forming part of Letters Patent No. 182,4 [3, datedSeptember 19, 1876; application filed August :21, 1576. y

To all whom 'it may concern:

Be it known that I, DAviD B. CHASE, of West Winsted, in the county ofLitchfield and State of Connecticut, have invented a new Improvement inFountain-Nozzles; and I do hereby declare the following, when taken inconnection with the accompanying d rawings and the letters of referencemarked thereon, to be a full, clear, and exact description ofthe saine,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a side view of the nozzle when the ow is out off; Fig. 2, avertical central section of the nozzle enlarged; Fig. 3, a trailsversesection of the saule; and in Fig. 4, a plan illustrating the operationof the nozzle.

This invention relates to an attachment for fountain nozzles, ltheobject being to dis-` charge a spray, and by the force of the dischargecause the nozzle to rotatle. It consists in combining, with a stationarynozzle or discharge, a iexible tube, terminatingv With a nozzleperforated transversely, the said perforations inclining bothlongitudinally and radially, as more fully hereinafter described.

The device is shown as applied to a common hose-pipe, A, made fast invertical position 5 but it may be applied to any discharge similarly`arranged. Bis a flexible tube or -common india-rubber nose, of such anature as to be extremely flexible. One end of this flexible part B isdrawn on over the tip of the nozzle. To the other end the discharge ornozzle proper C is attached. This nozzle C consists of acylindricaltube, its outer end wholly or partially closed, and o n the sides of thenozzle several perforations, a, are made. These perforations inclinelongitudinally inward from the end, or downward, as seen in Fig. 2. Theyalso have a radial incline,as seen in Fig. 3, the radial incline allbeing in the same direction. This completes the de- Vlce.

The loose pipe having been secured in a`vertions in Vthe tube C. Thejets discharging', as l indicated in broken lines, Fig. 3, through theinclined perforations, and impart to ita rotating or revolving force,while the longitudinal incline causes a reactionary force upon the tubeC toward the xcd nozzle A. i f

As the rotary or revolving motion of the tube C would twist the flexibletube, this force, combined with the longitudinal force, causes theflexible tube to swing around the tixed nozzle, the tube performing onefull revolution to each full swing around( the fixed point. The twist,therefore, which would be put into the flexible tube by the revolutionof the discharge-tube, will be taken out by the swinging around thefixed pointthat is to say, the swinging of the flexible tube around thisfixed point would twist the tube once around, if the free end did notrevolve,`and as the revolution of the tube by the force of the 'water isin the same direction as the twist which would be imparted to the tubeby such swinging around the fixed point, one twist counter-acts theother, the twisting force of the discharge vcausing the tube to swing inorder to free itself from the twist given it by the discharge.

I'claiin- In combination with a liexible discharge-` tube, the tubulardischarge,'pertbrated with openings inclined both longitudinally andradially, substantially as described.
